The X-linked 1.688 Satellite in Drosophila melanogaster Promotes Specific Targeting by Painting of Fourth
Repetitive DNA, represented by transposons and satellite DNA, constitutes a large portion of eukaryotic genomes, being the major component of constitutive heterochromatin. There is a growing body of evidence that it regulates several nuclear functions including chromatin state and the proper functioning of centromeres and telomeres. The 1.688 satellite is one of the most abundant repetitive seq...
متن کاملPainting and Society The Formation of the Persian Painting in the 14th Century
Persian painting has usually been studied from historical point of views. But its formation is rooted in a specific social context. In this study, we will try to contextualize it and we will show that this social context has a crucial role regarding its aesthetic. Persian painting is an art of royal courts and it represents the life of princes combined with Persian epic legendes. This social co...
متن کاملGenome-wide mapping of Painting of fourth on Drosophila melanogaster salivary gland polytene chromosomes
The protein Painting of fourth (POF) in Drosophila melanogaster specifically targets and stimulates expression output from the heterochromatic 4th chromosome, thereby representing an autosome specific protein [1,2]. Despite the high specificity for chromosome 4 genes, POF is occasionally observed binding to the cytological region 2L:31 in males and females [3] and two loci on the X-chromosome, ...
متن کاملPainting of fourth in genus Drosophila suggests autosome-specific gene regulation.
Painting of fourth (POF) is a chromosome-specific protein in Drosophila and represents the first example of an autosome-specific protein. POF binds to chromosome 4 in Drosophila melanogaster, initiating at the proximal region, followed by a spreading dependent on chromosome 4-specific sequences or structures. Chromosome-specific gene regulation is known thus far only as a mechanism to equalize ...
متن کاملTargeting of Painting of fourth to roX1 and roX2 Proximal Sites Suggests Evolutionary Links Between Dosage Compensation and the Regulation of the fourth Chromosome in Drosophila melanogaster
In Drosophila melanogaster, two chromosome-specific targeting and regulatory systems have been described. The male-specific lethal (MSL) complex supports dosage compensation by stimulating gene expression from the male X-chromosome, and the protein Painting of fourth (POF) specifically targets and stimulates expression from the heterochromatic 4(th) chromosome. The targeting sites of both syste...
